Hi Ben, The cards are four PCI Pinnacle PCTV Rave (Conexant FUSION 878A), i have checked if they work and they do without any problem with theyr own software that comes with the pinnacle drivers also if a run an standalone VIC they work. The 4 capturers are also being listed in the Computer Management. I'm at the moment installing Windows XP back as i installed Ubuntu to check, and as soon as i can i will mail again with screenshots attached but i'm pretty sure the only device that showed on the VideoProducer was the 'Microsoft WDM Image Capture'.
